The plan was a combined effort among scientists, TPWD staff, and conservationists to identify the needs of animal species and habitats as well as meet the required elements of the State Wildlife Grant Program (US Fish and Wildlife Service).

In the TPWD plan, mountain lions are classified as a species of concern and listed as imperiled in the state of Texas because of “their rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it [Mountain Lion] very vulnerable to extirpation from the state” (classification as imperiled (S2), pages 17 and 51 Section IV)) (TPWD, 2005).
